Need tutorial on 'this' sound

Klaas - How Does It Feel (Club Edit)

Ive been trying to achieve the sound throughout this song, which sounds like a bass and lead together.

I can achieve in the same ball park with my Korg EMX-1 automating the cutoff, but it doesnt sound right.

Could we please have a “how to sound like klaas” or could you give me some pointers?
